WILLIAM P. SUTTON, OF TORONTO, CANADA.

ELECTROMEDICAL APPARATUS.

SPECIFICATION forming part of Letters Patent No. 633,223, dated September 19, 1899.

Application filed November 25, 1898. Serial No. 697,471. (No model.)

To all whom it may concern/.-

Be it known that I, WILLIAM P. SUTTON, of

Province of Ontario, Canada, have invented certain new and useful Improvements in Electromedical Apparatus; and I hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to an electromedical apparatus by means of which a patient may be given an electromassage treatment; and

view of the complete apparatus. Fig. 1 is a plan view, partly in section, of the complete Fig. 2 is a transverse sectional view on the lines a a, Fig. 1. Fig. 3 is a cross-sectional view on the lines a. a, Fig. 2. Fig. 4 is a View of one of the electrodes.

Like letters of reference refer to like parts throughout the specification and drawings.

A represents the insulated base of the apparatus, which is made, preferably, of hard rubber or other suitable non-conducting material.

B B represent two electrodes rigidly fastened to the under side of the base A, with sufficient space between them to break the circuit of the current. Each electrode consists of a metallic plate having a plurality of cup-shaped sockets b. Contained in each socket iris an antifriction-ball b of conduct ing metal. Each socket b has an opening to allow of its respective ball projecting slightly beyond the metallic plate or cup shaped socket, the purpose of which is to provide the electrodes with a comparatively frictionless contact-surface. The edge of each electrode is provided with an upturned flange b.

O 0 represent two contact plates, each corresponding in size and shape with the, top of its respective electrode and heldin position by the upturned flange b" of its respective plate.

DD represent the binding posts of the contact-plates C C, respectively. By means of the contact plates the current is distributed evenly to the antifriction-balls of each electrode.

D represents the base of the magnet-frame,

and E represents the standard of the frame, connected to the-base D".

F represents a soft-iron core supported by the standard E. The core F projects beyond the standard E, and the projecting end is fitted with an anvil or field G.

H represents the armature attached to the end of an armature-spring I, connected to the bridge J, mounted upon the base D.

K represents the primary coil wound on the core F, one end of which leads to the bindingpost L and the other end of which leads to the binding-post L, connected to the bridge R.

M represents a hollow core, of fiber, celluloid, or other suitable non-conducting material, inclosing the primary'coil K and withdrawable therefrom. N represents a secondary coil wound on the core M, the ends of i which lead to the binding-posts D D of the contact-plates O C, respectively. The outer end of the coreM is provided with a cap 0, to which is connected an adj usting-screw O. The shank of the adj usting-screw 0' passes through a standard P, connected to the base A, and is fitted with a swiveled thumb-nut Q, by means of which the adj listing-screw is operated. By withdrawing the secondary coil from the primary coil the induced current through the secondary coil is diminished, and by replacing the secondary coil on the primary coil the induced current through the secondary coil is increased.

Rrepresents abridge connected to the base A, embracing the magnet above the armat-ure-spring I, and mounted on the bridge R is a lock-nut T. Passing through the locknut T and through the bridge R is a contactscrew U, having its point opposed to a contact-plate V on the armaturespring I. By means of the lock-nut T the extent of movement of the contact-screw U can be regulated and the operator prevented from unconsciously screwing the contact-screw against the armaturespring with sufficient force to bend it. The armature-spring I is provided with a binding-post in circuit with the contact-plate a of the commutator.

\V \V represent two batteries arranged one on each side of the magnet. The negative pole of the battery WV leads to the hinding-post L, while the positive pole leads to the contact-plate L of the commutator. The negative pole of the battery W" leads to the contact-plate L of the commutator, while the positive pole leads to the contact-plate L L represents a switch pivotally connected to the contact-plate a and adapted to engage either of the contact-plates L or L when it is desired to shunt the current.

By means of the two batteries the potential of the current through the primary coil can be increased or diminished at will, and the operation of the invention is as follows: \Vhen the switch L normally engages the contact-plate L, the current leads from the negative pole of the battery \V to the binding-post L, then through the primary coil to the binding-post L, to the bridge R, and from the bridge R, by means of the contact-screw U, through the armature-spring to the bindingpost 7, then to the contact-plate a, and through the switch L to the contact-plate L, and then back to the positive pole of the battery \V. \Vhen the switch is moved to the contact-plate L the current leads from the contact-plate a, through the contact-plate L to the positive pole of and through the battery WV. The current during its circuit generates a current of magnetism, which causes the attraction of the armature to the anvil and breaks the current through the contactscrew and binding-post \V and generates a secondary or reduce current, which passes through the secondary coil to the electrodes. The balls, as stated above, project slightly below the electrodes to form a comparatively frictionless rubbing-surface, and when these balls are in contact with the skin of the patient the current through the electrodes and secondary coil is closed. The balls by being of a eonductin g frictionless metal greatly reduce the frictional resistance during the use of the apparatus.

By providing the apparatus with a sliding secondary coil, as described, the potential of the current can be finely regulated to the sensibilities or strength of the patient.

Antifriction-rollers may be used instead of the antifriction-balls above described, and the electrode in this case would be altered so that the sockets would receive and retain the rollers.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
